Heavy duty, good functioning. Excellent quality! Well worth the bucks.

Same thing happened to me, I had an ASR-10 on top (two-tier extender), and an EX5 on bottom. The middle die-cast adjuster disintegrated and everything came crashing down. NOT happy.

I bought this stand based solely on its claimed 300 pound weight capacity. My 1965 Hammond B-3 chop comes in about 235. When the stand had been in use for about four hours, the "Patented Memory Lock System" disintegrated into seventeen pieces, the once-intelligent IQ-3000 collapsed, and the Hammond came crashing down to the floor. Fortunately it happened at home on a carpeted floor, and the mangled stand, along with the carpet, cushioned the fall. The mighty Hammond survived the drop with absolutely no damage or ill affects, which is just one of the many reasons the Hammond tonewheel organ is at the top of the keyboard food chain. I took what was left of this boat anchor (maybe strong enough to anchor a dinghy) to the nearest scrap yard and they told me THEY didn't even want it. I finally convinced them to take it, they gave me two bucks for it, and I wrote the whole thing off as a total loss.

The ONLY thing that stopped me from giving this stand the absolute lowest rating is that I feel it may be all right for most single manual, modern, digital keyboards. But for Ultimate Support to give this stand a 300 pound weight capacity is not using their IQ very wisely.

It did, however, Ultimately Support my Hammond on it's way down to the floor, cushioning the drop. Does that account for anything.........?

as a keyboard player that uses his stands as gymnastics equipment, this is the strongest stand i have ever used. it's able to support my MPK88 while i'm in a handstand or standing on top of the horizontal supports. i spend half of the entire set standing in the middle of the frame, and it doesn't flinch once. extremely sturdy and extremely stable.

I have a Yamaha S90XS and it is a beast. The first thing I needed was a new stand that would hold it and this does the job. It is really heavy duty and well made. The reason I can't give it 5 stars is accessories. The tubes are 2 inches instead of the standard size, this gives the extra strength. Sweetwater has been unable to find accessories to hold a mic boom stand, etc. Construction is superb. It can be used either sitting or standing in very comfortable heights. Once position is set you can fold it for easy travel and maintain the setting, which is great. If they could only get the accessories to fit it. Still I am very pleased with this stand and it is very high quality. Would certainly trust other Ultimate products based on the quality of this keyboard stand.

Really sturdy, seemed like a good match for my big and heavy keyboard. At the lowest setting (28.75 inches according to the specs) and accounting for the keyboard's thickness, the keys are over 32 inches from the floor, which is quite higher than my piano and way too high for my chair. Probably works fine for standing.
